LightSheetFluorescenceMicroscopeNewGenerationAlph
Alpha3 is a new generation of light sheet fluorescence microscope addressing the needs of high temporal resolution along with spatial high resolution to achieve qualitative and quantitative 3D imaging of fixed or live biological specimens.
From in‐vivo imaging to large cleared samples, the Alpha3 microscope delivers unprecedented image quality while keeping the necessary flexibility and modularity expected for cutting-edge scientific research instruments.
Patented Smart Light Sheet Illuminators
The light sheet system architecture comprises dual illumination units, each integrating multi-directional light sheet, combined with wide-field microscope detection, offering:
Real-time laser focus sweeping for optimized sharpness over the entire field of view
Removal of stripe artifacts for absorbing or scattering specimens
Ultrafast 3D acquisition with remote focal plane scanning
Flexible imaging system with a broad selection of detection objectives
Modular microscopy system for multimodal optical microscopy: FLIM, FRET, FRAP, photo ablation ...
Cleared mouse adipose tissue vascular network
Alphα3 features
Imaging flexibility, from in vivo imaging to large cleared sample imaging
Macro to micro view imaging, from whole organs at sub-cellular resolution to very small specimens
Compatible with all clearing solutions: aqueous buffers and organic solvents
Multiple mounting accessories to accommodate different sample natures and sizes
Unique live observation using optical eyepieces
Modular Light Sheet Microscope
The advanced sharp optical sectioning and smart scanning functions drastically alleviate spatial and temporal resolution constraints for 3D image acquisition in light sheet microscopy.
Sharp Optical Sectioning
The multidirectional light sheet illuminators perform real time focus sweeping to extend the thinnest focus area over the entire field of view, while improving homogeneity for artefact-free imaging.
Alpha3 microscope, with its innovative light sheet illuminators and system architecture, broadens the possibilities of life science imaging, providing new quantitative and qualitative imaging capabilities.
Smart 3D Scanning
The remote focal plane scanning technology combined with the dynamic illumination of light sheet planes allow for ultrafast Z-stacking and perturbation-free acquisition.

Cutting Edge Light Sheet Technology
The chamber allows for easy sample insertion and observation with air or immersion objectives. As biological specimens are of different nature and size, multiple sample holders are provided to accommodate a large variety of fixed or live samples.
In Vivo Imaging
In vivo imaging may require precise temperature and CO2 control as well as supplies of fresh medium for long term time lapse imaging.
The easily accessible chamber of Alpha3 is pre-equipped to maintain required environmental conditions during specimen imaging. The chamber support is provided with a circulation device that allows temperature control over a range of temperatures (from 15°C to 40°C). Thanks to the QtSPIM software, stacks of image data can be recorded for many hours or days for various applications such as developmental bio processes or stimuli response.
The architecture using a fluorescence microscope stand as a detection unit allows Alpha3 to flexibly adapt to any experiment setting. Complementary imaging capabilities can be easily added for multimodal microscopy.
Alphα3 features
Multiple accessories provided for sample mounting to accommodate a large variety of specimens
Chamber and sample holders highly resistant to corrosive media or clearing solutions
Low volume chamber minimizes evaporation and use of costly clearing solutions
Easy chamber access, allows addition of various experiment tools
In vivo imaging environmental controls
Flexible Sample Mounting
From sample mounting to image acquisition, Alpha3 performs seamless light sheet imaging. The QtSPIM software provides a clear and intuitive interface for collecting X, Y, Z, θ, T, λ images at maximum speed.
Raw image data, along with their metadata, are saved in 16 bits TIFF format (compatible with open source or commercial software for further 3D display and analysis).
QtSPIM controls all image acquisition parameters. When paired with a workstation grade computer in an optimized configuration, the system is able to perform ultra-fast acquisition.
Alphα3 features
Seamless X,Y,Z,θ,T,λ image data acquisition
Ultra-fast multichannel acquisition via a multi-notch filter, completed by a large selection of emission filters
Wide-field acquisition with sensitive high QE sCMOS camera
Wide choice of detection objectives: LWD 2X to 60X air, dipping lenses, clearing objectives with correction collar for RI matching
